There’s a Sleep Hack Sitting on Your Bookshelf

Bedtime Stories: You may think reading on your phone isn’t that different from reading on paper, and you’d be right for the most part, except when it comes to your sleep. Screens keep your brain alert late into the night, and research on reading before sleep suggests that trading a screen for a physical book is a small change that can really help.

How to Do It: Keep a book on your nightstand and make it the final step of your night, after putting your phone away and turning down the lights. It’s best to pick something calming instead of a thriller, since intense plots can keep your brain running even after you put the book down.

The Benefits: A study comparing people reading on an iPad vs. a printed book found that those using screens felt less sleepy in the evening and showed changes in brain activity tied to rest, even though both groups fell asleep in about the same amount of time. Another study found that older adults who read a book drifted off faster than those who kept their normal routine, and adults who read stories with a positive mood slept longer than the rest.
